Mark V Action — Features

Key details on the Mark V action, bolt, finish, and safety elements.

Mark V Action
The Mark V action uses a unique multi-lug bolt design (available as a six-lug Standard or a nine-lug Magnum) to increase strength while enabling a fast 54° bolt throw for quicker cycling.
Cerakote Finish
The barreled action is sealed with a durable Cobalt Cerakote finish to provide weather and corrosion protection while maintaining a low‑profile, wear‑resistant surface.
Fluted Bolt
The bolt is deeply fluted to reduce weight, help clear debris, and promote smoother feeding and extraction.
Safety Features
Integrated safety elements include a fully-encased bolt shroud and gas relief ports in the bolt body to protect the shooter from gas blowback and improve overall system safety.
Removable Bolt Knob
A removable bolt knob allows easy customization (different shapes/sizes or materials) and can be replaced or upgraded without changing the bolt assembly — useful for tailoring bolt manipulation to user preference or operating conditions.
